Well yes but the non-init function called has special behavior during bootstrap. initkmem_lists3 is not used after bootstrap. Everything would be fine if we could suppress the warning. > o Somebody who knows this code well needs to review and ack. On a IA64 system (allows up to 1024 node nodes) this will be wasting 212 kbyte. Some IA64 boxes only have 1 Gigabyte of memory. So we may end up wasting 1/5th of all available memory. - To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
